From cubicdissection.com:Daedalus by Gregory Benedetti is an utterly unique masterpiece of design. Brilliantly creative and brutally tricky, Daedalus hides its secrets well. The beautiful exterior gives no clue to the sheer pandemonium hiding inside. What appears to be a simple cube is an interlocking maze that continually changes its state with rotations, dead ends, and deception. Simple disassembly is a challenge; reassembly is genuinely an accomplishment.

Three unique pieces must be packed into a box with a restricted entry. Designed by Goh Pit Khiam and made by Tom Lensch.....

Leontev's 205 Minutes is a masterpiece in both design and construction. So named because if you make one correct move per second, non stop, it will take you 205 minutes to disassemble. This n-ary juggernaut requires over 12 thousand moves to disassemble. Once disassembled, a reset mechanism allows you to quickly bring it to the original state with only four moves. It also comes with the 136 minute piece which only requires around 8,000 moves to solve.It was a difficult decision to make this puzz...

BurrBon is an utterly unique Interlocking Burr Puzzle. What could be better than a six-piece burr? How about a six-piece burr inside another six-piece burr? There are several ways to build the inner and out burrs separately, but only one possible configuration assembles them together. The interaction between inner and outer pieces is what makes this an extraordinarily difficult puzzle.The construction of BurrBon required just the right balance of tolerances to allow the inner burr to move smooth...

The goal of Fano Blocks is to pack seven pairs of identical rectangular pieces flush into the box. These aren't just any pieces, however! They possess unique properties: any two distinct blocks share precisely one edge length in common and any set of two specific edge lengths are held by two identical blocks. The resulting number of edge-matching combinations creates a complicated problem. Finding even one of the eight possible solutions is an accomplishment.Named after the Fano plane (the small...
